Hello, Thank you for playing. Imagine its like a matching game. First time you are in the room, that is your safe a room(= if you are in this version of a room, you can exit trough the "safe" exit) if you are in other rooms, they have details changed and that means you should exist trough danger exit on the other side.
As for mechanism, you are looping randomly in couple versions of the level and there is a counter of correct guesses that will go to zero if you guess incorrectly. I originally planned to do it bigger in scope, but time is not your friend in jams as I am sure you know :)
